It can actually reproduce either sequence from which the delta was generated. But this is really trivial: ndiff was intended to produce diff output for humans to read, and includes the full text of both input sequences in "the diff" it generates. > Unfortunately, restore does not do the same for unified_diff.

That's in general impossible, since unified diffs generally omit most lines that compared equal to begin with. Unified and context diffs are, in part, compression gimmicks, showing only what changed plus a bit of context. ndiff shows everything, so can restore everything too. -- http://mail.python.org/mailman/listinfo/python-list
